Microstructural Stability of Ti based Composites Fabricated by Spark Plasma Sintering [PDF]
MATEC Web of Conferences, 2020 In our previous study, the effects of TiC heterogeneous nucleation site particles on formability and microstructure of additive manufactured (AMed) Ti-6Al-4V products were studied.

Heterogeneous nucleation in the low-barrier regime [PDF]
Physical Review E, 2013 In simulations of the 2D Ising model, we examine heterogeneous nucleation induced by a small impurity consisting of a line of $l$ fixed spins. As $l$ increases, we identify a limit of stability beyond which the metastable phase is not defined. We evaluate the free energy barrier for nucleation of the stable phase, and show that contrary to expectation,

Heterogeneous Nucleation and Grain Initiation on a Single Substrate
Metals, 2022 Recently, we have proposed a new framework for early stages solidification, in which heterogeneous nucleation and grain initiation have been treated as separate processes.

Heterogeneous Nucleation in and out of Pores
Physical Review Letters, 2006 We study the nucleation of a new thermodynamic phase in pores and find that the nucleation often proceeds via two steps: nucleation of pore filling, and nucleation out of the pore. These two rates have opposing dependencies on pore size, resulting in a pore size at which the nucleation rate of the new phase is maximal.

Effect of Heterogeneous Nucleation on Removal of Arsenic from Molten Steel by Rare Earth Addition
Metals, 2020 Cleanliness control is an eternal theme to improve the properties of steel products. With the increasing recycling rates of scrap steel, the removal and stabilization of residual elements have become a vital issue for improving the performance of steel ...

Sensitivity studies of dust ice nuclei effect on cirrus clouds with the Community Atmosphere Model CAM5 [PDF]
Atmospheric Chemistry and Physics, 2012 In this study the effect of dust aerosol on upper tropospheric cirrus clouds through heterogeneous ice nucleation is investigated in the Community Atmospheric Model version 5 (CAM5) with two ice nucleation parameterizations.

Heterogeneous Ice Nucleation by Graphene Nanoparticles [PDF]
Scientific Reports, 2020 AbstractNanostructure, chemical composition and size distribution of aerosols have prime important effects on their efficiency in heterogeneous ice nucleation (HIN). The ice nucleation usually requires active sites in the aerosols in order to act as ice nuclei (IN).
